The overheating protection feature
halts driver operation to protect the
battery pack in the event of over-
heating. The overheat warning lamp
on the control panel flashes when
this feature is active.
• If the overheating protection feature
activates, allow the driver to cool
thoroughly (at least 30 minutes).
The driver is ready for use when the
overheat warning lamp goes out.
• Avoid using the driver in a way that
causes the overheating protection
feature to activate repeatedly.

Excessive (complete) discharging
of lithium ion batteries shortens their
service life dramatically. The driver
includes a battery protection feature
designed to prevent excessive dis-
charging of the battery pack.
• The battery protection feature acti-
vates immediately before the bat-
tery loses its charge, causing the
battery low warning lamp to flash.
• If you notice the battery low warning
lamp flashing, charge the battery
pack immediately.
